Programming interview flashcards & study guides - printable PDF + Anki decks
Flashcards for developers, made by a developer who sat on both sides of the interview table.
I'm Sławek, a senior software engineer from Wrocław, Poland. For more than 15 years I've built backend systems in Java for banks and trading platforms - and along the way I've been on both sides of the tech interview table more times than I can count: as the nervous candidate, and as the interviewer deciding who gets the job.
That's where FlipCards started. Preparing for interviews, I kept turning thick books and scattered blog posts into something my brain could actually retain: short questions, precise answers, repeated until they stuck. Flashcards - the oldest study trick there is - turned out to work better for interview prep than anything else I tried. So I made proper decks of them. First for myself, then for friends, and in time it grew into flipcards.pl, a small shop back home in Poland where thousands of Polish developers have studied from my cards.
This store is the English-language home of those decks. Every card is written and curated by me - a working engineer who interviews real candidates - not generated filler. I started gathering flashcards long before AI became a thing. I keep answers short enough to memorize, honest about what interviewers actually want to hear, and current with the language (yes, including the features that got withdrawn - those make great trap questions).
Each pack comes in three formats, because people study differently: printable cards you can cut out and shuffle in your hands, an Anki deck for spaced repetition on your phone, and a condensed cheat sheet for the final review before you walk in.
If a card ever feels unclear or outdated, message me - I read everything and update the decks. Good luck in the interview. You're better prepared than you think.
